After installing the unit, show the user how to turn 
off the electricity to unit.  Point out control and 
switch locations for turning off the electricity.

  

Make sure user understands the importance of 
following all safety precautions. 

 

1. 

NOTICE & DISCLAIMER 

As originally manufactured, this unit contains refrigerant 
installed by the manufacturer.  The manufacturer  uses only 
refrigerants that have been approved for use in the unit’s 
intended country or market.  The manufacturer’s distributors 
similarly are only authorized to provide refrigerants that have 
been approved for use in the countries or markets they serve.  
The refrigerant used in this unit is identified on the unit's 
faceplate and/or in the associated manuals.   Any additions of 
refrigerant into this unit must comply with the country’s 
requirements with regard to refrigerant use and should be 
obtained from  the manufacturer’s  distributors.   Use of 
unapproved refrigerant substitutes will void the warranties and 
can cause injury or death. 

DISCLAIMER 

Customer modifications to ENVIRO-TEC certified products are 
prohibited.  

The manufacturer has certified the product as being compliant 
with applicable government and/or industry standards. Product 
certification is designated either on the product itself or in the 
product literature. The certification mark identifies the 
applicable standards as well as the Nationally Recognized 
Test Lab (NRTL) or other testing facility that conducted the 
testing, where applicable. If changes are made to the product, 
an engineering review will be needed to assess the impact to 
the product certification. In some instances, the changes may 
be such that the NRTL or testing facility will need to review and 
potentially re-approve of the product by means of a field or site 
inspection and certification. Any person or entity making 
changes to the product is responsible for obtaining any 
necessary engineering review and re-approval. Unauthorized 
customer modifications to ENVIRO-TEC  products are 
prohibited for the following reasons: 

A. 

Modifications may create hazards which could result in 
death, serious injury or equipment damage.  

B. 

Modifications will void product warranties.  

C. 

Modifications may invalidate product certifications. 
Modifications may violate Country standards. Country 
standards may require that only certified products be 
used in certain applications, and modifications that result 
in the loss of product certification may violate those 
standards.

 

2. 

PREPARING TO INSTALL UNIT 

A. 

Literature 

Review this Manual and the Users’ Manual Information.   

After installing the unit; give this Installer’s Information Manual 
to the end user.  If you need help on any of the installation 
instructions or other matters relating to the unit, contact the 
office where you bought the unit.  You may also refer to the 
unit rating plate for a contact name. 

B. 

Shipping 

Cabinets  and risers  are  shipped in  one of the  following 
configurations: 

A. 

Risers are attached to cabinet, and cabinets are stacked 
on their side. Chassis ships on separate skids. 

 

 

B. 

Risers ship loose packaged in boxes and sorted by floor. 
Cabinets ship upright up to 4 per skid. Chassis ships on 
separate skids. 

C. 

Risers ship loose in  packaged  boxes, sorted by floor. 
Cabinets ship upright on skids with chassis inside cabinet 
(chassis  electrical and water connections are  not 
installed).  Cabinet must remain standing upright. Do not 
place cabinets on their side with chassis inside. Chassis 
is secured to service panel. Remove screws before 
removing service panel and chassis. 

C. 

Inspection & Storage 

Cabinets, chassis and risers should be stored in the same way 
they were shipped. Store in a dry area and ensure chassis 
units are always in their upright position.  If risers are being 
stored at the job site ensure the ends are capped to prevent 
contamination.   

In areas where construction is not complete—including dry 
walling, plastering, painting, and where emission of dust 
particulates or fumes from out-gassing are present—all 
precautions must be taken to protect the cabinet, cabinet 
openings, and chassis from physical damage and 
contamination by foreign material.

 

A. 

Check the unit for indications of damage in shipment.  
Notify the Transportation company of any damage and 

note the damage on the shipping receipt.   

Rough handling may dislocate and damage internal 
components. 
 
 
 
 

B. 

Check riser projections at each end of the cabinet for 
misalignment or end damage that would prevent making 
an acceptable connection. 

C. 

Thermostats and other accessories which have been 
shipped separately should be inspected for quantity and 
transit damage. 

D. 

Store the refrigeration chassis in the normal upright 
orientation to maintain oil in the compressor sump. 

D. 

Pre-Installation 

A. 

Verify the model number on the unit nameplate with the 
ordering and shipping information, to ensure the correct 
unit has been shipped.  

B. 

All cabinets may not be equipped with the same size 
riser, or the same air supply grille arrangement. Carefully 
inspect each unit before delivery to the installation site. In 
most cases, each cabinet will be individually tagged for a 
specific location in the building.  

C. 

Keep the cabinet sealed with the shipping materials until 
all plastering, painting and construction work is complete.  

D. 

Remove the inner service panel, and manually check the 
blower wheel for free rotation. 

E. 

Match the refrigeration  chassis to the proper cabinets by 
referring to the cabinet and chassis nameplate and label 
information. 

F. 

Remove the chassis  refrigeration access panel  (top 
cover)  and inspect the unit. Ensure that the refrigerant 
tubing is free from obvious physical damage  and kinks, 
and 

check  that  piping  does not touch other unit 

components
